Overview: Acoustic Partition Roll (APR)
The acoustic insulation properties of glass mineral wool results in specialist sound reducing products that are available for use in new build separating walls, partitions, and floors, as well as for the upgrade of existing buildings to provide improved sound insulation and resistance.
Knauf Insulation acoustic insulation rolls have been especially developed to utilise the sound absorption properties of glass mineral wool.
While the thermal insulation properties of glass mineral wool are maintained, for these products, this is usually considered a secondary benefit, as their primary purpose is to improve the acoustic insulation performance of the solutions in which they are used.
Key reasons for the use of these products are: reducing airbourne sound transmission (e.g. through partition walls) reducing impact sound transmissions (e.g. through upper floors) reducing sound reverberation in specialist environment (e.g. recording studios)
Knauf Earthwool Acoustic Roll
Earthwool Acoustics Roll are ideal for insulating internal floors, separating floors, internal walls and plasterboard partitions.
Acoustic Performance: Earthwool Acoustic Roll has exceptional acoustic absorption properties.
Fire Performance: Knauf Acoustic Roll is classified as Euroclass A1 to BS EN 13501-1.
Earthwool Acoustic Roll is a flexible glass mineral wool quilt which is lightweight, flexible, resilient and non-combustible.
Earthwool Acoustic Rolls are 1200mm wide and ready-cut to produce three, 400mm wide rolls, or two, 600mm wide rolls and manufactured to a minimum density of 10Kg/m3.
Excellent sound absorption properties
Lightweight, and easy to install
Dimensioned to suit studs and joists at 400mm or 600mm centres
Long roll lengths for quick and economic Installation
Friction fits between studs, ensuring continuity of the absorbent layer with no air gaps
Earthwool Acoustic Roll is specifically designed for friction fitting between joists and studs at 400mm and 600mm centres to improve the sound insulation of:
- Separating walls and floors
- internal walls and floors
- timber and metal stud partitions
It is also designed for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls.
And, provides a high level of sound absorption, whilst also improving the thermal and fire performance of the wall, floor or partition. Using glass mineral wool as a sound absorbent layer in partitions and floors significantly improves their acoustic performance, whilst only adding minimally to the overall mass of the structure.
In partitions glass mineral wool complements the plasterboard linings by absorbing airborne sound in the cavity and reducing reverberation, it is particularly effective at preventing the hollow sound that can occur in partitions with unfilled cavities.
Knauf Acoustic Roll represents no known threat to the environment and has zero Ozone Depletion Potential and zero Global Warming Potential.
Earthwool Acoustic Roll is manufactured in accordance with BS EN 13162, EN 16001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems, as certified by Bureau Veritas.
Knauf Acoustic Roll is odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria.
Knauf Acoustic Roll offers negligible resistance to the passage of water vapour and has a vapour resistivity of 5.00MNs/g.m.
Handling and storage
Knauf Acoustic Roll is easy to handle and install, being lightweight and easily cut to size, where necessary.
It is supplied in polythene packs which are designed for short term protection only.
For longer term protection on site, the product should be stored either indoors, or under cover and off the ground.
Knauf Acoustic Roll should not be left permanently exposed to the elements.
